[0002] With the rapid development of industry, the types of protective clothing are becoming more and more diverse. According to the airtightness, they can be divided into breathable protective clothing, semi-permeable protective clothing and non-breathable protective clothing.

[0003] Existing airtight (semi-permeable) protective clothing has poor air permeability or even no air permeability, which leads to an increase in the relative humidity of the microclimate under the protective clothing, which in turn leads to the following problems:

[0004] (1) When the wearer wears airtight (semi-permeable) protective clothing, the heat emitted by the human body in the enclosed space cannot be quickly dissipated to the external environment and is stored in the protective clothing, which increases the core temperature of the human body, thereby stimulating sweating and increasing the risk of dehydration.

[0005] (2) When the water vapor in the airtight (semi-permeable) protective clothing reaches saturation, sweat droplets will form. The accumulation of sweat droplets reduces human comfort. In order to cope with this uncomfortable environment, the human body needs to increase heart rate, respiratory rate, blood pressure and body temperature, thereby increasing fatigue and affecting work efficiency.

[0006] In summary, how to provide a dehumidification device for reducing the humidity of the microclimate under airtight (semi-airtight) protective clothing is a problem that needs to be urgently solved by those skilled in the art. Summary of the invention

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The core of the present invention is to provide a dehumidification device, which has a flexible structure and can have a certain amount of deformation, and can be placed in protective clothing to reduce the humidity of the microclimate under the airtight (semi-permeable) protective clothing. Another core of the present invention is to provide a protective clothing including the above-mentioned dehumidification device.

[0038] Please refer to Figure 1-Figure 5 .

[0039] This specific embodiment discloses a dehumidification device, comprising:

[0040] A flexible outer package, which is made of waterproof material and at least partly of waterproof and breathable material;

[0041] The desiccant 13 is sealed in the flexible outer package.

[0042] It should be noted that the waterproof material of the flexible outer package can prevent liquid water from entering or flowing out, but gaseous water vapor can enter the flexible outer package through the waterproof and breathable material.

[0043] The desiccant 13 may be a calcium chloride desiccant 13, or may be other materials that meet the requirements and have a drying effect, which is determined according to actual conditions.

[0044] The flexible outer package has a certain deformation during use, and can be bent, folded, etc., and its normal use will not be affected by extrusion deformation.

[0045] The shape and size of the flexible outer package need to be determined according to actual conditions and will not be elaborated here.

[0046] The flexible outer package can be made of the same material, for example, the entire flexible outer package is made of waterproof and breathable material, or it can be made of spliced ​​materials, for example, one side of the flexible outer package is made of waterproof and breathable material and the other side is a waterproof film, or other splicing settings, which are determined according to actual conditions.

[0047] In the process of using the dehumidification device provided in this specific embodiment, the flexible outer package has a waterproof and breathable material. When the humidity in the environment is high, air can enter the flexible outer package through the waterproof and breathable material, and the desiccant 13 absorbs moisture in the air, thereby achieving a hygroscopic effect and reducing the humidity in the environment.

[0048] Compared with the prior art, since the initial device provided in this specific embodiment has a flexible outer casing, during use, the flexible outer casing has a certain amount of deformation and can be placed in the protective clothing to reduce the humidity of the microclimate under the airtight or semi-permeable protective clothing.

[0049] In a specific embodiment, the dehumidification device further comprises:

[0050] The phase change structure 5 is provided with a phase change outer package and a phase change material filled in the phase change outer package, and the phase change outer package is connected to the flexible outer package, and is used to absorb the heat generated by the desiccant 13 after absorbing moisture.

[0051] During use of the dehumidification device provided in this specific embodiment, the desiccant 13 releases heat during moisture absorption. The phase change structure 5 can be used to absorb the heat generated by the desiccant 13 after moisture absorption, which can effectively avoid temperature rise and maintain the temperature within a suitable range.

[0052] It should be noted that the phase change material mentioned in this specific embodiment refers to a material that changes its state and provides latent heat without changing the temperature; the process of changing physical properties is called a phase change process, and the phase change material will absorb or release a large amount of latent heat during this process.

[0053] Preferably, the phase change material is paraffin alkane, and the dehumidification device uses paraffin alkane phase change material. Paraffin alkane phase change material has good circulation, no overcooling, no precipitation, stable chemical properties, no corrosion, and high heat of dissolution. It is a better choice for oral phase change material; it can also be other phase change materials that meet the requirements, which will be determined according to actual conditions.

[0054] Preferably, the phase change outer package can be set as a flexible structure, and the phase change structure 5 can be set between the inner side 8 of the protective clothing and the flexible outer package; specifically, the edge of the phase change outer package can be pressed and fixed with the edge of the flexible outer package through a plastic sealing and pressing process to connect the phase change outer package with the flexible outer package.

[0055] In a specific embodiment, the flexible outer package includes a plastic film 6 close to the phase change structure 5 and a waterproof breathable membrane 7 facing outward and in contact with the air. The edge of the plastic film 6 is sealed to the edge of the waterproof breathable membrane 7 to form a sealed space inside for storing the desiccant 13.

[0056] like Figure 1 As shown, the plastic film 6 and the waterproof breathable membrane 7 are arranged correspondingly, and the edge of the plastic film 6 is sealed and connected with the edge of the waterproof breathable membrane 7 through a processing technology to form a bag-like structure, and a desiccant 13 is filled in the structure composed of the plastic film 6 and the waterproof breathable membrane 7 to form a flexible bag-like dehumidification device with a certain deformation amount.

[0057] Preferably, the flexible outer package is a flat bag-like structure, which occupies a small space and is convenient to use.

[0058] In this specific embodiment, one side of the flexible outer package is a waterproof and breathable membrane 7, which can allow air to fully contact with the desiccant 13 to provide a dehumidification effect.

[0059] In the specific production and assembly process, the plastic film 6 can be bonded to the waterproof breathable film 7 and the phase change structure 5 by a plastic sealing machine. Of course, other production methods can also be used, which are determined according to actual conditions. Preferably, the edge of the phase change structure 5 is sealed and connected to the edge of the flexible outer package, so that the phase change structure 5 is completely attached to the plastic film 6 surface of the flexible outer package to enhance the heat absorption effect.

[0060] On the basis of the above embodiment, a plurality of sealing separation seams 11 may be provided in the flexible outer package, and the sealing separation seams 11 are used to compress and seal the plastic film 6 and the waterproof breathable membrane 7, so as to separate the sealed space into a plurality of mutually independent sealed compartments 9;

[0061] The sealed compartments 9 are filled with desiccants 13 , and at least one side of the sealed compartments is a waterproof and breathable membrane 7 .

[0062] like Figure 2 As shown, a plurality of sealed partitions 11 are provided to divide the sealed space into a plurality of mutually independent sealed compartments 9. The provision of the sealed partitions 11 divides the desiccant 13 into a plurality of portions, and the desiccant 13 is located in different sealed compartments 9, which can effectively prevent the desiccant 13 from agglomerating together, thereby increasing the contact area between the desiccant 13 and the air, improving the moisture absorption efficiency, and realizing rapid dehumidification.

[0063] like Figure 2 As shown, the sealing separation seams 11 include a plurality of first sealing separation seams and a plurality of second sealing separation seams, and the first sealing separation seams and the second sealing separation seams are perpendicular to each other. Of course, the first sealing separation seams and the second sealing separation seams may not be arranged perpendicularly, and a single sealing compartment 9 may be a pentagon, a triangle, a quadrilateral or an irregular shape, and the sizes of the plurality of sealing compartments 9 may be the same or different; the specific size is determined according to the actual situation and will not be elaborated here.

[0064] In a specific embodiment, if Figure 2 As shown, the single sealed compartment 9 includes a drying compartment 91 for filling the desiccant 13 and a water storage compartment 92 for filling the water absorbing material 15 ; the drying compartment 91 is connected to the water storage compartment 92 so that the liquid after the desiccant 13 is dissolved can flow into the water storage compartment 92 .

[0065] like Figure 2As shown, the drying compartment 91 and the water storage compartment 92 are separated by a non-sealed separation seam 10 to prevent the desiccant 13 from mixing with the water absorbing material 15. Figure 3 As shown, after the desiccant 13 is decomposed, the decomposed desiccant 13 can flow into the water storage compartment 92 through the inflow channel 14 in the non-sealed partition 10, and the water-absorbing material 15 absorbs the decomposed desiccant 13 to prevent the decomposed desiccant 13 from shaking in the dehumidification device and affecting the user experience.

[0066] Preferably, the water-absorbing material 15 is a highly water-absorbent resin. When the desiccant 13 is liquefied, the liquefied desiccant 13 is absorbed by the highly water-absorbent resin, thereby avoiding the problem of solution shaking due to movement.

[0067] In order to enable the dehumidification device to be smoothly installed on the protective clothing, a fitting portion can be provided on the side of the phase change structure 5 away from the flexible outer package, and the fitting portion can be a structure such as Velcro 12, double-sided tape, etc. Figure 2 As shown, Velcro 12 can be set around the dehumidification device to improve the firmness of the fit so that the dehumidification device can be detachably attached to the protective clothing. During use, the structure composed of the flexible outer packaging in the dehumidification device and the desiccant 13 inside it is a disposable device, and the phase change structure 5 can be recycled and reused. The dehumidification device provided in this application document can be suitable for disposable protective clothing or reusable protective clothing; when suitable for reusable protective clothing, the structure composed of the flexible outer packaging and the desiccant 13 inside it can be discarded after use, retaining the phase change structure 5, and replaced with a new structure composed of the flexible outer packaging and the desiccant 13 inside it.

[0068] In addition to the above-mentioned dehumidification device, the present invention also provides a protective suit comprising a protective suit main body and a dehumidification device arranged in the protective suit main body. The dehumidification device here is the dehumidification device disclosed in the above-mentioned embodiment. For the structure of other parts of the protective suit, please refer to the prior art and will not be repeated in this article.

[0069] Specifically, Figure 1 , 2 As shown, a single protective suit can include a first dehumidification device 1, a second dehumidification device 2, a third dehumidification device 3 and a fourth dehumidification device 4. The first dehumidification device 1 is located on the upper right chest of the protective suit body, the second dehumidification device 2 is located on the lower left chest of the protective suit body, the third dehumidification device 3 and the fourth dehumidification device 4 are respectively located on the left side and the right side of the backpack of the protective suit body; of course, the appropriate dehumidification position can also be selected according to medical physiological indicators, ergonomics, airtight (semi-permeable) protective suit structure, etc., which can be determined based on actual conditions.

[0070] like Figure 1As shown, the protective clothing is provided with an oblique zipper, and the lower side of the first dehumidification device 1 is at the same height as the upper side of the dehumidification device; Figure 2 As shown, the third dehumidification device 3 and the fourth dehumidification device 4 are installed at the same height.

[0071] The “first”, “second”, “third” and “fourth” in the first dehumidification device 1, the second dehumidification device 2, the third dehumidification device 3 and the fourth dehumidification device 4 mentioned in the present application document are only for distinguishing the different positions and there is no order of precedence.
